Karma Vipaka Samhita 95.15

गायत्रीसूर्यमन्त्रेण लक्षजाप्यं वरानने ॥

Let him do one hundred thousand japa (repeating a mantra) with the Gayatri (a sacred Vedic chant). Add the Sun mantra, O fair-faced one. Then let…

दशांशं भोजयद्विप्रान् ब्राह्मणान्वेदपारगान् ॥

Let him feed brahmins who have mastered the Vedas, with a tenth part. A pumpkin and a coconut with the five jewels

गङ्गामध्ये प्रदातव्यं देवि सत्यव्रताय च ॥

should be given in the middle of the Ganga, O Goddess, to a man true to his vow. When this is done, O fair-faced one, all disease comes to an end.
